SHADE-HOLDER.

To all whom it may concern:

Be it known that I, GEORGE B. THOMAS, a citizen of the United States ofAmerica, and residing at Bridgeport, inthe county of Fairfield and Stateof Connecticut, have invented a certain new and Improved Shade-Holder,of which the following is a specification.

My invent-ion relates to shade holders and partici'ilarly to means forsecuring a holder to its support, the object of my invention being toprovide a simple and inexpensive device for locking the shade holder ona lamp socket or other suitable support.

In the accompanying drawings, made to an enlarged scale for the purposeof better illustration, Figure 1 is a vertical section through myimproved shade holder show* ing the same mounted upon a lamp socket; andFig. 2 is a perspective of the shade holder parts detached and inposition for` mount-ing upon its support.

The globe or shade supporting means carried by the holder' form no partof my invention and may be of any suitable character. In the form shownthey comprise the usual set screws 5, threaded through the dependingperipheral iange 6 of the holder.

The means employed for mounting the holder upon the support are asfollows: Integral with the body .of the holder I form an upwardlyextending neck portion 7, which is beveled at its inner upper edge 8 toconform to the contour of the bead 9, formed as usual at the lampreceiving end of the shell 10 of the lamp socket. The neck 7 isexternally threaded to receive the locking ring 11, which is of greaterdiameter than the neck and which may be passed over the bead 9 on thesocket shell. A spring ring 12 of any suitable construction is sprungover the bead 9 and is engaged by the inwardly projecting flange 13 atthe upper edge of the' locking sleeve 11, when the latter is screweddown upon the neck 7 of the shade holder.

The method of assembling the parts is readily understood. The lockingsleeve 11 having been passed over the lamp receiving end of the socketshell to a position above the bead 9, the spring ring 12 is thenadjusted above the bead and the holder pushed up on the socket until itsbeveled edge 8 engages with the lower surface of the bead 9. The lockingsleeve l1 is then brought Specification of Letters Patent.

down into position to be threaded upon the neck 7. Obviously as thesleeve is screwed down upon the neck 7 the bead 9 is clamped between theflange 13 and ring 12 on the one hand, and the neck 7on the other hand,so that the holder is securely locked in position.

To facilitate the screwing and unserewing of the sleeve 11, upon theneck 7, I provide a recess 1.4L in the sleeve 11 which may be engaged bythe end of a Spanner or other instrument. Any other suitable means forfacilitating the screwing down of the locking sleeve may be provided.

I claim asmy invention l. A shade holder having a depending peripheralflange, shade holder engaging means carried thereby, an upwardlyextending externally threaded neck adapted to engage the lower face of asupporting bead, a split ring adapted to lic above said supporting bead,in combination with an internally threaded locking sleeve of greaterdiameter than the neck oit' said holder and adapted to be passed overthe supporting bead and brought down into threaded engagement with saidneck, together with an inwarglly projecting [lange at the upper edge ofsaid sleeve adapted to engage said spring ring when screwed down uponthe neck of said holder.

2. A shade holder having a depending peripheral flange, shade holderengaging means carried thereby, an upwardly extending externallythreaded neck adapted to engage the lower face of a supporting bead, andbeveled on the inner face of its upper edge to correspond to the shape0f said bead, a split ring adapted to lie above said supporting bead, incombination with an internally threaded locking sleeve of greaterdiameter than the neck of said holder and adapted to be passed over thesupporting bead and brought down into threaded engagement with saidneck, together' with an inwardly projecting flange at the upper edge ofsaid sleeve adapted to engage said spring ring when screwed down uponthe neck of said holder.

rlhe con'lhination with a standard socket having a circumferential bead,of a shade holder having an abutment member lying to one side of saidbead, a cooperating abutment member lying to the other side of saidbead, one of said abutment members being of greater diameter than saidbead, a filling piece between said bead and the abutment member ofgreater diameter and means for drawing said abutment members together tolock the shade holder to said bead.

4. In a device of the character described,

`the* combination with a shade holder body having an abutment adapted tobe juxtaposed to one side of a supporting bead, of a cooperatingindependent abutment member adapted to be juxtaposed to'the oppositeside of said supporting bead, a filling piece interposed between one ofsaid abutment members and the supporting bead, and

'means for drawing said abutment members means for drawing said clampingmembers together to lock the holder to the bead.

6. A shade holder comprising a body portion with peripheral flange,shade holding means carried by said flange, a central threaded neck withabutment adapted tov engage the'lower side of a supporting bead, aspring ring adapted to lie above said bead and a cooperating threadedsleeve with inturned Flange lying above said ring in adjusted positionand in threaded engagement with said neck, serving to draw said memberstogether to lock the shade holder to the bead.

7. A shade holder having cooperating clamping members adapted to lieabove and below a supporting bead, one of said members comprising amember of greater diameter than said bead and a filling piece interposedbetween said clamping member and bead in adjusted position, incombination with means for drawing said clamping members together tolock said holder -to said bead, substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses.

GEORGE B. THOMAS.
